Public images listed by default

[hvelarde]

Public images should only be listed when using the --public flag:

I thought that doctl compute image list should return all images, not depending on status, but looks like I'm wrong. As looking at the code, this could be a bug, as default is really false for public images.

I'll send PR containing a fix right now, looks like I found where it is, just to test it.

Edit: PR published.
